China ON-SITE (IN-SITU) EMC TESTING and EMC debug

Test Methods of Electromagnetic Compatibility In-situ for Large Medical Equipment or System 【ON-SITE (IN-SITU) EMC TESTING】

Electromagnetic compatibility testing of medical equipment in my country has been mandatory. Large medical equipment or systems often have characteristics such as large size, inconvenient transportation, relatively fixed installation, and large rated power supply current (here specifically refers to each phase current greater than 16 A), such as MRI, DR , cascade biochemical analyzers, high-power sterilizers, hyperbaric oxygen chambers, etc.

This type of equipment is more complex than conventional medical equipment in terms of test layout and cable connections. Due to the special requirements of the installation environment and usage environment, some equipment or systems are often inconvenient to conduct electromagnetic compatibility testing in a laboratory environment, and the equipment needs to be tested and evaluated at the installation site.

Similarly, there are large industrial equipment systems (for example, various large energy storage cabinets, charging stations, heavy industry equipment, large frequency converter cabinets, drying ovens, high-power motors, etc.), etc. due to fixed installation, large size, and inconvenient transportation. , large rated power supply current, and even some require separate other auxiliary support systems, etc., it is often impossible to complete electromagnetic compatibility testing in the laboratory. At this time, EMC on-site testing needs to be performed at the customer’s product site.

GZSA can provide one-stop technical services such as on-site EMC testing, non-conformity EMC debug, standard technical consultation, and registered inspection reports in China and across the country.

EMC Testing

What is EMC?

EMC (Electro Magnetic Compatibility): Literally translated as “electromagnetic compatibility”, it refers to the ability of the electromagnetic energy generated by the equipment to neither interfere with other equipment, nor to interfere with the electromagnetic energy of other equipment. EMC includes EMI and EMS.

EMI (Electro Magnetic Interference): Literally translated as electromagnetic interference, it refers to the electromagnetic disturbance it emits to the outside world. This is a compound word, we should consider “electromagnetic” and “interference” separately. The so-called “interference” refers to the two-layer meaning of the performance degradation of equipment after interference and the source of interference to the equipment. The first meaning is like thunder and lightning causing noise on the radio, snowflakes appearing on the TV screen after a motorcycle is driving nearby, and radio sounds are heard after picking up the phone, etc.

EMS (Electro Magnetic Susceptibility): Literally translated as “electromagnetic susceptibility”, it means the ease with which electromagnetic energy can cause performance degradation. To make it easy to understand, we compare electronic devices to people, and electromagnetic energy to cold viruses. Sensitivity is whether or not you are susceptible to catching a cold. If you are not susceptible to catching a cold, it means that you have strong immunity, which is the English word Immunity, which means strong resistance to electromagnetic interference.
